Tenant moving out early

[Chris Gilliam]

Hey Guys, have a newbie question. I have a rental property that the tenant signed a 1 year lease in August then called me and said they have to move in December cause the husband lost his job. So i worked out a deal and wrote up a Conditional Lease Termination Agreement. Over the phone we agreed to the terms and set a time to meet to get them to sign the lease term agreement. Well when i got over there they were not there and when I looked in the window it appears they have moved. Just some odds and ins left in the house. I have text messages stating they are moving. My question is how long before i can take back the house? Do I need to post anything for certain amount of time since i have txt messages stating they are moving today. On a second note i do plan on taking them to court for breaking the lease and for the "Stop Payment" they put on the money order for November's rent.

Thanks for your advise in advance,
Chris
